Dear Marcus Holland-Moritz,

This is a computer-generated report for Convert-Binary-C-0.78
on perl 5.20.1, created by CPAN-Reporter-1.2018.

Thank you for uploading your work to CPAN.  However, attempting to
test your distribution gave an inconclusive result.

This could be because your distribution had an error during the make/build
stage, did not define tests, tests could not be found, because your tests were
interrupted before they finished, or because the results of the tests could not
be parsed.  You may wish to consult the CPAN Testers Wiki:
